This study examined the long-term performance and life span of mixture designs with a high percentage of reclaimed asphalt pavement (RAP) (≥30%) used on higher-tonnage (>5,000 tons) projects. The pavement performance of mixtures containing high RAP

The presence of pore water in mixtures can cause premature failure of hot-mix asphalt pavements. The processes typically associated with moisture damage are complex and occur over a long period of time in the field. Short of being able to simulate ea

Current test methods specify that the angle of gyration of a Superpaver gyratory compactor (SGC) be measured externally or outside of the mold. The external angle of gyration may not accurately portray the actual angle inside the mold during compacti

Failing volumetric properties (low air voids and voids in mineral aggregate) have been a common occurrence in the production of Superpave mixes in Florida and nationally. There are several potential causes of this problem including the effect of asph
